AudioMoth low cost audio recorders

[Yowie_Nakamoto]

Hi Guys,
I've been looking into audio recorders and found these: https://www.openacousticdevices.info/
They are very cheap at just $120AUD or thereabouts and look pretty simple/easy.

I just wanted to ask if a) anyone else has used one or b) if anyone else wants one (or more) as I plan to make an order.

Let me know.
Cheers,
YN
